19.25 works on Ultrix 4.2. The 19.26 pretest was reported to work
on Ultrix 4.2a and on 4.4.
One user reported 19.25 did not work at all with --with-x-toolkit
using X11R5 patch level 10, but worked ok with X11R5 pl26.
See under Ultrix for problems using X windows on Ultrix.
Note that this is a MIPS machine.
For Ultrix versions 4.1 or earlier, you may need to define
SYSTEM_MALLOC in `src/m/pmax.h', because XvmsAlloc.o in libX11.a seems
to insist on defining malloc itself.
For Ultrix versions prior to 4.0, you may need to delete
the definition of START_FILES from `src/m/pmax.h'.

Some sysV.3 systems seem to have bugs in `opendir';

Mips (mips-mips-riscos, mips-mips-riscos4.0, or mips-mips-bsd)
The C compiler on Riscos 4.51 dumps core trying to optimize
parts of Emacs. Try without optimization or try GCC.
Meanwhile, the linker on that system returns success even if
there are undefined symbols; as a result, configure gets the
wrong answers to various questions. No work-around is known
except to edit src/config.h by hand to indicate which functions
don't exist.
Use mips-mips-riscos4.0 for RISCOS version 4.
Use mips-mips-bsd with the BSD world.
Note that the proper configuration names for DECstations are
mips-dec-ultrix and mips-dec-osf.
If you are compiling with GCC, then you must run fixincludes;
the alternative of using -traditional won't work because
the definition of SIGN_EXTEND_CHAR uses the keyword `signed'.
If the SYSV world is the default, then you probably need the following
line in etc/Makefile:

Some operating systems on MIPS machines give SIGTRAP for division by
zero instead of the usual signals. The only real solution is to fix
the system to give a proper signal.
In the meantime, you can change init_data in data.c if you wish.
Change it to handle SIGTRAP as well as SIGFPE. But this will have a
great disadvantage: you will not be able to run Emacs under a
debugger. I think crashing on division by zero is a lesser problem. reported needing to use --x-libraries=/bsd43/usr/lib

general or only because of quirks on a particular site.
